Braddon Liberal MHR Brett Whiteley has hit out at enviro group Save the Tarkine in paliament.

"Two weeks ago, I received a letter from an inner city Melbourne law firm seeking the immediate payment of $40,000 and an apology for standing up for the people of Braddon and attacking the Save the Tarkine group for its job-destroying stunts,'' Mr Whiteley told parliament last night.

"Let me say clearly and loudly tonight to Save the Tarkine directors, Scott Jordan, former Senator Bob Brown and Bleyer Lawyers: I will not be silenced.

"I will not back down and I will not stop until Save the Tarkine pays taxpayers and Venture Minerals back for its failed court cases and ceases its job-destroying campaign through the courts.''
